1. A detector device, comprising a processor that
determines a plurality of first estimates of an angle of detection from a plurality of first receiver antennas separated by a first spacing between adjacent ones of the first receiver antennas;
determines a plurality of second estimates of the angle of detection from a plurality of second receiver antennas, the first and second receiver antennas being physically arranged in a one-dimensional linear array and the second receiver antennas being staggered with the first receiver antennas within the one-dimensional linear array such that each second receiver antenna is offset from a center of the first spacing between adjacent ones of the first receiver antennas on opposite sides of the second receiver antenna;
identifies which one of the first estimates is closest in value to one of the second estimates; and
determines an angle of detection of the detector device from at least one of the identified one of the first estimates and the identified one of the second estimates;
wherein the processor determines the plurality of first estimates and the plurality of second estimates by using a multiple-dimension array angle determination technique and treating the first and second receiver antennas physically arranged in the one-dimensional linear array as a multiple-dimensional array with the first receiver antennas arranged in a first linear array of the multiple dimensional array and the second receiver antennas arranged in a second linear array of the multiple dimensional array.
